PARC NATIONAL DE LA GARAMBA. — MISSION H. DE SAEGER en collaboration avec P. BAERT, G. DEMOULIN, I. DENISOFF, J. MARTIN, M. MICHA, A. NOIRFALISE, P. SGHOEMAKER, G. TROUPIN et J. VERSCHUREN (1949-1952). Fascicule 33 (2) ENDOMYCHIDAE (COLEOPTERA POLYPHAGA) BY H. F. STROHECKER (Miami) Although the northeastern part of the Congo Republic is near the nor- thern limit of endomychid distribution in Central Africa, the intensive col- lecting of the De Saeger Expédition has resulted in the capture of more than 15.000 specimens. Most of these are referable to the genus Danaë, but several other genera are represented. I wish lo thank Henri De Saeger for making these specimens available for my continuing study of the Endomychidae. Grant G-9023 from the Uni¬ ted States National Science Foundation has accelerated the survey of this material and enabled me to clarify taxonomie problems through study of the Gorham and Arrow types in the British Museum, and the Pic types in the Paris Museum. 1. — Subfamily EUMORPHINAE.

Study of maie aedeagi shows that five forms, probably species, of Ancy¬ lopus (s.s.) occur in Africa. The distribution of these is puzzling and requi- res additional study. The Senegal specimen, of which the aedeagus is figu- red, has the coloration described by Gerstaecker, i.e. ferruginous with two small, black spots on each elytron. The Garamba maies have the aedeagus essentially identical, but the elytra black, each with two red spots. Collection notes indicate that this species is associated with low végéta¬ tion, especially grasses. Before me are 375 maies and 183 females.

Most of these were taken from dead wood in forest. One note describes the forest as of guinean type. A few records cite capture on trees in wooded savanaa, and two specimens were taken from low savanna végétation. Collection Nos. 934, 1508, 2112, 2188, 2298, 2746, 2942, 3068, 3115, 3190, 3367, 3475, 3499, 3622, 3826. 15. — Trycherus arrowi Villiers. Villiers, Bulletin I.P.A.N.

Reiche, in Perret et Galinier, Voyage en Abvssinie (1847), III, p. 408. Study of the Gorham, Arrow and Pic types permits considérable clarifi¬ cation of the taxonomy of this difficult genus. The collections from Garamba Park contain thousands of specimens. While the maies offer good spécifie characters, I cannot be certain that assignments of females are allogether correct. *16.
